This invention relates to lasting machines, and

is herein illustrated as applied to a power-operated toe-lasting machineconstructed generally as disclosed in United States. Letters Patent No.2,160,846, granted onJune 6,1939 on an application of F. C. Eastman andA. F. Pym, but modifled in certain respects in accordance with thedisclosure of UnitedStates Letters Patent No. 2,371,146. granted onMarch 13, 1945 on an application oi mine. It is to be understood,however, that the invention is not limited tomachineor ganizations ofthat particular character.

The machine shown in the above-mentioned Letters Patent No. 2,160,846 isprovided with wipers which are swung about an axis extending widthwiseoi the lastto wipe the toe-end portion theupper on the wipersat thesides of the toe earlier in the upwiping operation than in theconstruction above described. thus increasing its eifectiveness'on theupper in those locations. As herein illustrated, an arm and a-link whichcooperate to tip the retarder into position to clamp the upper on thewipers first at the end or the toe have a lost-motion connection betweenthem 7 by reason of which the retarder is permitted to of the upperheightwise oi the last and are then operated to wipe the marginalportion of the upper inwardly over an insole on the last. and also withgrippers which apply a pull "to the toe end of the upper and control itduring the greater portion of the wiping operations of the wipers. Inaccordance with the disclosure of Letters Patent No. 2,371,146 there wassubstituted for such grippers a device having the iunction or what iscommonly known as a retarder, the device being arranged to clamp themarginalportion of the upper outspread on the wipers at'the end and thesides of the toe and to cooperate with them in applying a pull to theupper while preventing the formation of any objectionable wrinkles inthe upper in the course of the toe-lasting operation. Since a shoe priorto the toe-lasting operation is commonly lasted at the sides of theforepart beyond the toe portion, and since themargin oi the upper may,therefore, be more readily outspread and clamped on the toe wipers atthe end of the'toe than at the sides of the toe near the previouslylasted portions when the wipers are in the positions which they occupyat the beginning of the wiping oi the upper heightwise of the last (commonly known as the upwiping operation), the retarder shown in thelast-mentioned Letters Patent was mounted to tip about an axis extendingwidthwise of the last and was connected to mechani sm for thus tippingit into position to clamp the upper onthe wipers first at the endo! thetoe and for thereafter progressively tipping it in the reverse directionin the course of the upwiping operation to bring it into position toclamp the upper on the wipers also at the sides 01' the The presentinvention, in accordance with one of its features, provides aconstruction such that tip reversely early in the upwiping operation inresponse to pressure of the upper thereon and is permittedthereaf-ter tomaintain a position parallel to the wipers during their further upwipingmovements.

In accordance with another feature, the invention provides novel meansfor moving the retarder "be smoothly and tightly outspread on thewipers.

In the construction shown the retarder is mounted on a bar which extendsheightwise of the last and is movable bodily with the retarder by thewipers in the upwiping operation, and in response to that movement ofthe bar it is swung lengthwise oi the last by a cam to impart theoutward wiping movement to the retarder. The cam serves also to guidethe retarder into proper relation to the last and the wipers in itsmovement into up? per-clamping position. To cause the retarder torelease the margin of the upper alter the wipers begin their movementsto wipe it inwardly over the insole the bar supporting the retarder ismoved farther heightwise of the last while still under the influence ofthe above-mentioned cam, and the retarder, moreover, is tippedrelatively to the bar about an axis extending widthwise of the last, asin the construction shown in Letters Patent No. 2,371,146, to releasethe upper first at the end of the toe while continuing the pressurethereon longer at the sides of the toe. To avoid any tendency for theparts to cramp at this time the cam is so mounted and controlled as topermit it to move yieldingly in response to resistance of the upper atthe sides of the toe to the tipping of the retarder.

The above and other features of the invention, including also novelmeans for variably timing the movements of the retarder toward and fromupper-clamping position and various novel details ofconstruction andcomputations of parts, will now be more particularly described with re!-erence to the accompanying drawings and thereafter pointed out in theclaims.

the retarder assumes a position for clamping Inthc drawings,

Fig. 3 is a view partly in right-hand side elevation and partly insection, showing the parts in the positions which they occupy prior tothe beginning of the movements of the wipers and the retarder;

Figs. 4, 5 and 6 are views similar to Fig. 3, illustrating the positionsof the parts at different times in the course of the operation of themachine; and

Fig. 7 is mainly a plan view showing the parts in the same positions asin Fig. 5.

In view of the disclosures in the above-mentioned Letters Patent, onlysuch portions of the machine will be herein described as it is necessaryto refer to for an understanding of the invention. The position of theshoe, herein shown as one of the welt type, is determined by engagementof a member 2 with the bottom face of the toe end of the insole and withthe inner face of the lip of the insole at the end and the sides of thetoe. The shoe is clamped against this member by a toe rest 4 which ismoved upwardly into clamping position, as illustrated in Fig. 3,substantially at the beginning of the cycle of power operations of themachine. For lasting the toe end of the shoe there are provided wipers 6which are advanced and closed to embrace the upper about the toe end ofthe last and are swung upwardly about an axis extending widthwise of thelast to wipe the upper heightwise of the last. Thereafter the wipers arefurther advanced and closed to wipe the marginal portion of the upperinwardly over the feather and against the lip of the insole, the lipbeing supported against the inward pressure of the wipers by the member2.

As in the machine shown in the previously mentioned Letters Patent No.2,371,146. the grippers disclosed in Letters Patent No. 2,160,846 forap- I plying a pull to the toe end of the upper and for controlling itin the toe-lasting operation are dispensed with, and instead there isprovided a retarder 8 arranged to clamp the marginal portion of the toeend of the upper outspread on the wipers and to control the upper in thecourse of the wiping movementsof the wipers. This retarder is supportedon the lower end of a bar It) extending heightwise of the last andhereinafter more particularly referred to, and is constructedsubstantially as disclosed in Letters Patent No. 2,371,146. Briefly, itcomprises a pair of upper-clamping members I2 each arranged to engagethe upper along one side and part way around the end of the toe, and acentral upperclamping member I4 arranged to bridge any space between thetwo members I2 at the end of the toe. The two members I2 are mounted ona rod I6 for adjustment toward or from each other in directionswidthwise of the shoe, this rod being secured to the lower end of thebar I0. Thecentral member Ills provided at the opposite sides of the barI0 with a pair of ears l8 whereby it also Is mounted'on the rod I6, andit is arranged to overlap and. engage flat faces on the two members I2so that all three members are held in fixed relation to one another formovement as a unit about the rod I6. For adjusting the two members I2toward or from each other there are provided two latch members 20slidingly mounted on a rod 22 secured to the bar I0, these latch,members'belng arranged to extend into grooves 24 (Fig. 2) formed inportions of the members H which are located above the rod I6. Threadedon the opposite end portions of the rod 22 are nuts 26 each providedwith a flange 28 arranged to lie in a groove formed in the hub of thelatch member 20 associated therewith. The latch members are-normallyheld in the grooves 24 by springs 30, but may be swung against theresistance of the springs to release the members I2 and permit thelatter to be removed from the rod I6 if desired. It will be evident thatthe members I2 may be adjusted eachv independently of the other alongthe rod I6 by the nuts 26.

The bar In which supports the retarder 8 is pivotally supportedsubstantially midway between its lower and upper ends, by means moreparticularly hereinafter described, on one arm 32 of a three-armed lever34 loosely mounted on a rockshaft 36 supported in bearings on the frameof the machine. Another arm 38 of the lever 34 is connected by a spindle40 to one arm 42 of a two-armed lever 44 which in the constructionherein shown is fast on the rockshaft 36. The spindle 40 is mounted toturn in a trunnion block 46 pivotally mounted on the arm 38' and isthreaded in another trunnion block 48 pivotally mounted on the arm 42.By means of a collar 56 and a hand wheel 52 engaging the trunnion block46 on its opposite sides the spindle is prevented from moving lengthwiserelatively to this block, and accordingly turning movement thereofserves to adjust the arm 32 and the bar I0 either in a downward or anupward direction to vary the initial position of the retarder 8heightwise of the shoe. Fast on one end of the rockshaft 36 (Fig. 1) isan arm '54 connected by a downwardly extending link 56 to one arm 58 ofa bell-crank lever 60 mounted to turn about a shaft 62. The other arm 64of this. bell-crank lever is provided with a roll 66 in engagement withthe periphery of a cam 66 fast on the main cam shaft III of the machine.A spring 12 connected to the arm 64 tends to swing the bell-crank lever60 in a counterclockwise direction (Fig. 1) and holds the roll 66normally against the cam. At the proper time in the operation of themachine a drop a on the cam 68 permits the spring 12 to swing the lever60 in the direction to impart downward movement through the rocksha'ft36 and the arm 32 to the-bar I0 and the retarder 8 and thus to move theretarder into position to clamp the margin of the upper outspread on thewipers 6 (Fig. 4). In this operation the spring 12 is assisted byanother spring 14 (Figs. 1 and 3) connected at its lower end to thesecond arm 16 of the two-armed lever 44 and at its upper end to a lever18 which is used adjustably to vary the tension of the spring 14 andcorresponds to the lever 54 shown in United States Letters Patent No.2,354,663, granted on August 1, 1944 on an application of mine. It willthus be seen that the upper is clamped on the wipers by the combinedforces of the two springs I2 and I4 and that the clamping pressure maybe varied by adjusting the tension of the spring 14.

Mechanism similar in many respects to that disclosed in Letters PatentNo. 2,371,146, but different in other respects, is provided forcontrolling the retarder as to movement about the rod I6 and for tippingit about the rod in the course of its downward movement toward thewipers to cause it to clamp the upper on the of the shoe and pivotallyconnected at their forward ends by pins 84 to upwardlyextending portionsof the previously mentionedears I8 on the I centralretarder member.These two arms-82 v are secured near their rear ends to the oppositesides of another rearwardly extending arm 86, by

v a bolt 88 extending through slots 96 in the, arms 82 to permit theeffective length of the link 80 to be Varied. In the construction hereinshown the arm 86, .which serves as the rear portion of the link 80,- isprovided with a. slot 92.through which extends a stud .94 threaded in athird arm 9670f the three-armed lever .34. .A head on this stud overlapsthe arm 86to maintain it in assembled relation to the arm 96. Connectedto the bolt 88 and to the stud .94 is a comparatively light'spring 96which through its action on the link 80. tends I may be so adjusted asto eliminate any lost moto turnthe retarder; 8 in: a'clockwise direction.(Fig. .3) about the rod I6 and holds th link normallyin a position. inwhich the stud 94 is at the forward end of the slot 92, as illustratedin Fig.3;

When therockshaft 9,6 is turned as above do:- I

scribed to move the retarder downwardly toward the wipers, the arm 96.acts through the spring 98 on-the link 80to tip the retarder abouttherod I6 into position to cause it to clamp the upper .on

.the wipers'first at the end of the toe, as illustrated in Fig.4,.thestud 94, s-till remaining at the forward end of the slot 92; i

' After the upper has been clamped 0n the'wipers at. the end of the toeas above described, the wipersin their upwiping movements serveto liftthe. retarder and the bar I0, causing the-rockshaft 36 to turn inthereverse direction, 1. e., in a clockwise direction with reference; toFig. 4,

against the resistance ofthe springs I2 and 14. By reason of thisturning movement of the rockshaft the arm 96 acts through the stud 954tomove the link.80 toward the 1eft (Fig. 4) to tip the re-- tarderin acounterclockwise direction about the rod I6, thereby causing theupper-clamping face of the retarder to approach'a position parallel tothe plane of the wipers. shortly'after the beginning of this tippingmovement of theretarder the pressure of the upper thereon becomeseffective further to tip it quickly in the samedirec tion, ,because ofthe fact that the upper-engagingportionofthe retarderat the end of thetoe becomes tarderby the upper is permitted by the slot 92 andi's'effected against the resistance of the light spring 98, the link 8.0assuming a position in which the stud 94 is spaced from the forward endof the'slotfas shown in Fig. 5. In this mannor the retarder iscaused; toassume a position parallel to the wipers, so as to clamp the upper atthesides as well as at the end ofthextoe,

farther ofiset laterally from the axis of I ther'od'l6ij This furthermovement of the re-' tion between thelink 80 and the arm 96, so that theretarder will be fully controlled by the arm 96 as to tipping movementabout the rod I6, in accordance with the manner of operation dis--closed in the last-mentioned Letters Patent.

I Shortly after the wipersbegin their-movements to wipe the marginalportion; of the upper ine Wardly over the insole a rise 17 on the cam 68arrives in position toengage the 101166 and to turn the rockshaft 36still farther in a clockwise direction to lift the bar I9 and thus tocarry the retarder away from the upper. In this operation the arm 96acts through the stud 94 and the link 80 to tip the retarder in acounterclockwise direction, so that it releases the margin of the upperfrom pressure first at theiend of the toe, as shown inFig. 6,whilecontinuing effective clamping pressure thereon longer at the sides ofthe toe. Accordingly the wipers and the retarder cooperate to exert apull on the upper longer at the sides of the toe as its marginal portionis being wiped inwardly over, the insole, which helps to guard againstthe formation of any objectionable wrinkles in the upper inthoselocations. It

willbeunderstood that continued movement of the rockshaft serves toreturn the parts to the positions in'which they are shownv in Fig. 3.

In the construction herein'shown the cam 68 (Fig. 1) includes twoadjustable plates I02 and I04 formed respectively to provide thepreviously mentioned drop a and the rise-b. These plates are adjustableeach independently ,of the other about the axis of the shaft I0 and areheld in adjusted= -positions by clamping screws I06 extending throughslots I98 in the plates. It will be understood that by adjustment of theplate I02 the time in the cycle of operations of the machine whentheretarder starts to move downwardlytoward the wipers maybe varied,thereby varying relatively totheupwiping movements of the wipers thetime when the retarder becomes I effective to clampthe upper thereon.'By'adjusting-"the plate ,IM the time when the retarder starts to leavethe upper in the course of the overwiping movements of the. wipers maybe similarly varied. v

, Furthertto'control the retarder with respect to movements lengthwiseof the shoe, there is provided'a cam. block III) having therein a camslot I.I2"in which lies a roll I-I I mounted on the ed in the rear end"of the arm .86 of the link 80 is a stop screw I00 arranged vto en a ethefside' of the stud 94 and thus to limit the'lost motion v between thelink and thearm 96. By adjustment of this screw; thereforgthe timein theupwiping operation when the retarder assumes a position parallel tothewipers maybevaried in accordance withfthe character (Jr/condition of thework. It will beevident that during the further upward swinging movementof; the wipersafter theretarder has effectively clampedthe upper at thesides of the toe, the retarderwill maintain its parallel relation to thewipers by reason-of PP QK l tY qrded by the-slot; 9? r for; the

upper end'of the bar III. The lower portion of this cam 'slot isinclined-in such manner that during the latter portion of the downwardmovement of the bar and the retarder toward the wipers the bar is swungin-a clockwise direction (Fig. '4.) about its connection with the arm 32and jtherebymoves the retarder in a'heelward direction to position itproperly within the pocket rovidedby the outwardly inclined to-endportion i of the upper-and close to the toe-end face of the last whenitclamps the upper on the Wipers.

Contributing to this result'also is the factthat as the retarder ismoved downwardly-it is tipped in a clockwise clirection about the rod I6in the manner hereinbefore described. When. the retarder and the bar H!are lifted by the wipers in the upwiping "operation, the lower portion.of the camislo't' I i2-serves'to swing the bar I0 reverselyLandi'therebyto impart to the retardera bodily movement outwardly overthe wipers in wiping engagement with. the margin of the upper; Thisoutward wiping action of the retarder on the upper'supplements a similaraction due to its previously described swin'gi ng movement about therodl6, ahd'a'ffords increased insurance that the margin of theupper'will be smoothly outs'pread o'n thewipers and will be held tightbetween the edges of the wipers and the last. Such outward wipingmovement of the retarder as takes place after the retarder has assumed aparallel relation to the wipers does not disturb that relation becauseof the lost-motion connection between the link 8i) and the arm 56. Theupper portion of the cam slot H2 is so inclined that during the latterportion of the upward'moveme'nt of the retarder in its return tostarting position the bar lflis swung in a clockwise direction toprevent inter'ference between'the link 80 and the arm 32. Consequently,during the first portion of the downward movement of the retarder towardthe shoe the upper portion of the cam slot swings the bar In in thedirection to carry the retarder to-v ward the rear of the machine priorto the control of the bar by the lower portion of the cam slot.

To guard against cramping of the parts when the retarder is tipped asshown in Fig. 6 and starts to leave the upper at the end of the toe, thecam block H is pivotally mounted at its upper end on a pin H6 supportedon a portion I I8 of the frame of the machine and is controlled by aspring I20 against the resistance of which it may swing about the pin inresponse to pressure of the roll H4 on the rear wall of the lowerinclined portion of the cam slot I I2. The spring IZllis mounted betweena downwardly extending lug I22 on the frame I I8 and the forked head INof a rod I26 pivotally connected to the cam block by a pin I28 andextending rearwardly through an'opening in the lug I22. A nut 13!) onthe rod determines by engagement with the lug I22 the normal position ofthe cam block with respect to movement about the pin H6. Since thetipping of the retarder eiTected by the link 80 as the bar L ll] beginto move upwardly to withdraw the rethese-movements-ofthe wipers the dropa on the cam .68 arrives in position opposite the roll 66 I and theretarder 8 is moved downwardly toward the wipers by. the action of. thesprings 12 and T4 onlthe rockshaft 36. As the retarder is thus moveddownwardly it is guided into proper position relatively to'the margin ofthe'upper and. the toe end oftheiast by the action of the cam slot M2on? the bar in, and it is also'tipped about th'erod 16' by the arm 96acting through the spring 98 on the link 80,. so'that it' assumes aposition for clamping'the upper on the wipers first at the end of thetoe, .as shownin Fig. 4. The retarder may become effective thus to clampthe upper on the wipers substantially at the time whenithe wipers intheir upward swinging movementsv arrive in positions to begin aneffective upwiping action: on the'upper. Thereafter, durin'g'theupwiping"operation, the retarder and the bar ID are lifted by the wipers, theretarder cooperating with the wipers to apply an upward pull to theupper while its margin slips more or less inwardly over the wipers. Byreason of the lifting of the bar I!) the rockshaft 36 is turned in aclockwise direction and the roll 66 is swung away from-the cam 68. Asthe retarder begins to be-lift'ed' by the wipers from the position inwhich it is shown in Fig. 4, the arm 96 acts tarder from the upper isaccelerated by any further swinging movement of the bar at this time bythe cam block H0, the provision for yielding movement of the cam blockpreventsthe retender 'from'binding unduly on the upper at the sides ofthe toe by reason of its tipping movement.

The pivotal connection between the bar I0 and the arm 32 comprises aneccentric l3 2 (Fig. 2) on which the bar is mountedLthis eccentric beingformed on a pin I34 which is mounted in the forked front end of the arm32. One of the forks. of this arm carries a stud I36 having in one sidethereof a curved recess I38 which en'- gages the periphery of anenlarged portion of the pin I34, and on the lower end of this stud isthreaded a nut I40 by which the stud may be moved lengthwise to securethe eccentric I32 in through the link to tip it in the reverse'directionabout the rod [6, and shortly after the beginning-of this tippingmovement the pressure of the upper on-the retardercauses it quickly totip-farther in the same direction against; the resistance of the light"spring 98, as permitted by the slot 92 in the link 80, The retarder thusassumes a position parallel 'to the wipers, so that it"clamps the-upperon the wipers at the sides as well as at'the end of the toe, asillustrated in Fig.5; at a time which maybe not long after thebeginningof the upwiping operation. Thereafter, during the rest of theupwiping operation, the retarder maintains its parallel relation to thewipers by reason of the provision afforded by the slot 9 2 for-the link"80 to move relatively to the arm*'9 6.; During the upwiping operation,moreover. the-lower portion of the cam slot llz'serves to swing the barH) in the direction to cause the retarder to wipe the margin of theupperoutwardlyover the wiperspthis action supplementing the outwardwiping action due to the tipping of the retarder about the rod I-B.Following the upwiping operation, the wipers are further advanced andclosed to wipe the marginal' portion of the upper-inwardly over thefeather and against the lip of the insole, and shortly after thebeginning of their inward movements the rise b on the cam 68 begins toact on the roll 66 to turn the rockshaft 36 farther in a clockwisedirection and thus to lift the bar land to 'carry'th' retarder away fromthe upper. At the same time the arm 96 acts through the link 80 to tipthe retarder in a counterclockwise direction, about the rod I 6, causingit to release the upper from pressure first at the end of th'e'toe whilecontinuing the pressure longer at as new and desire tos by LettersPatent of 'theUnited Statesis: a
